Does gas I pay for end up staying in the hose?

Asked by mrentropy (17213points) August 8th, 2009

So I was getting gas today and it hit me that the hose for the pump goes down then curves up to where my filler spot is. I wasn’t going for a fill-up so when I stopped pumping I started to wonder if gas was still left in the hose.

Should I be lifting up the hose to drain the last bits of gasoline from there, or does the pump have some kind of mechanism to take care of that?

If indeed this is the case then only the first user to the hose would be ripped off because when you came along you got what was in the hose from the prior buyer.

Only if you are the very first person to ever use the pump.

It’s just a little left for the next person, who leaves a little for the next person, etc etc etc.

Think of it as a chain of eternal, anonymous secret santas…

gosh I feel odd today haha

I have actually seen the advise to manually lift the hose at the machine end, to get the last drop out, but as the other people here have pointed out, you begin with whatever is already in the hose.

All great answers, and they make sense. However, if someone ahead of me is smart enough to drain the hose then I don’t get that bonus. On the other hand, if they don’t and I lift the hose when I’m done then I get a super-bonus.

I’m not sure that that’s the case at all – what about pumps that deliver both diesel and gasoline using the same hose? Don’t you think it’d be a little risky to allow the possibility of a hose-worth of diesel get into an engine that might be damaged by it? That would even be the case without diesel being present – if I pay for high octane, am I really going to get the fuel that’s already in the hose – no matter what rating that is?

There is no such thing as a nozzle that deliveres both gasoline and diesel. The ends on them aren’t even the same size (to prevent people from being able to accidentally put diesel into a gas engine).

I stand corrected. Must be going crazy. /sigh

@Akiora In your defense, there are different grades of gasoline, so there is some danger of contamination, but the guy ahead of you might have used the highest grade.

shake it out like from the top of the hose thing. it, at least, makes it not drip when you pull it out. that sounds bad sorry

I put diesel in my vehicle by accident once. Had to drain the whole darn tank.
